• Blackberry JDE generating bad .jad file (does not match compiled .cod file)

  - by matkas

  I Have a BB application that gets compiled into 3 siblings cod file. ( actualy one cod fil contaning 3 sub cod files). app.cod |--app.cod |--app-1.cod |--app-2.cod which is normal. the jad refers to those 3 inner .cod files. Now I have add some feature to my app, it is getting a little bit bigger. the jad now refers to 4 inner .cod files. but there is still 3 inside the app.cod that is generated. so I now still have app.cod |--app.cod |--app-1.cod |--app-2.cod but with the jad refering to app.cod app-1.cod app-2.cod AND app-3.cod. what is wrong the my compiled program? is it a bug from the JDE? I am using JDE 4.5.

• Rails app is prepending tunnlr web address when using link helpers

  - by mathee

  I set up facebooker to tunnel my Ruby on Rails application. The issue is that I would like to test locally. That is, I don't want to have to start a tunnel every time I want to see my changes. Right now, when I start the application using ruby script/server (not calling rake facebooker:tunnel:background_start beforehand), links created by helpers (e.g., stylesheet_link_tag, javascript_include_tag, image_tag) are prepended with my tunnlr address: http://web1.tunnlr.com:myPort/. (For example, a CSS link looks like this in the page source: http://web1.tunnlr.com:myPort//stylesheets/appName.css?1234567890.) I don't want that functionality; I can't see my CSS or JavaScript changes without starting the tunnel first. I want the links to be relative to what's running on my machine, not the tunnel. So, stylesheet_link_tag should produce /stylesheets/appName.css?1234567890. Does anyone know why it's doing that in the first place and how to fix it? Thanks in advance.

• How to allow users to define financial formulas in a C# app

  - by Peter Morris

  I need to allow my users to be able to define formulas which will calculate values based on data. For example //Example 1 return GetMonetaryAmountFromDatabase("Amount due") * 1.2; //Example 2 return GetMonetaryAmountFromDatabase("Amount due") * GetFactorFromDatabase("Discount"); I will need to allow / * + - operations, also to assign local variables and execute IF statements, like so var amountDue = GetMonetaryAmountFromDatabase("Amount due"); if (amountDue > 100000) return amountDue * 0.75; if (amountDue > 50000) return amountDue * 0.9; return amountDue; The scenario is complicated because I have the following structure.. Customer (a few hundred) Configuration (about 10 per customer) Item (about 10,000 per customer configuration) So I will perform a 3 level loop. At each "Configuration" level I will start a DB transaction and compile the forumlas, each "Item" will use the same transaction + compiled formulas (there are about 20 formulas per configuration, each item will use all of them). This further complicates things because I can't just use the compiler services as it would result in continued memory usage growth. I can't use a new AppDomain per each "Configuration" loop level because some of the references I need to pass cannot be marshalled. Any suggestions?

• Making an animated taskbar app

  - by CasperT

  Hi. I have a HP notebook (running XP). I have seen on IBM computers, that they have a power-meter (it looks like a bar). It displays percentage of power left in battery. It is displayed in the taskbar. Not in the systemtray. Either on the left side or the right side of the potential language toolbar. The application is animated, since the percentage of power (0-100%) chances. It fills up the bar with a green color according to the percentage. So half would be colored green if the power is down to 50%. Now, since it is an IBM application for IBM notebooks, I want/need to make a copy of it. My real question is though, how do I make an animated taskbar application?

• MVC app not working on server but is fine on development machine

  - by GB

  Hello, I am able to run my application just fine on my dev machine but as soon as I publish it to the web server some functionality is lost. Any type of .ajax POST does not work usually with a 401 unauthorized error. The server is Windows 2008 with IIS7. I also installed Visual Studio 2008 with MVC2 on the server and ran the application directly on the server and the same .ajax POST does not work but the error changed to 500 unknown. Thanks for the help.

• Right way to create [self]respawning app in python

  - by grapescan

  I am using jabber bot written in python to log some MUC talks. Sometimes it drops on some network or XMPP problems. In this case I have to start it again by myself. The goal is to make it "self-respawning". I have some variants about how to do it. Bot is one process. Another process monitors its activity and starts it if bot died. Main process spawns bot subprocess and controls it. Also I think daemonizing bot process is useful here. Platform is Linux, as you could guess. What is the right way to solve this problem?

• Run Exchange Management Shell cmdlets from Visual Basic/C#/.NET app

  - by nowarninglabel

  Goal: Provide a web service using Visual Basic or C# or .NET that interacts with the Exchange Management Shell, sending it commands to run cmdlets, and return the results as XML. (Note that we could use any lanaguage to write the service, but since it is a Windows Box and we have Visual Studio 2008, it seemed like easiest solution would be just use it to create a VB/.NET web service. Indeed, it was quite easy to do so, just point and click.) Problem: How to run an Exchange Management Shell cmdlet from the web service, e.g, Get-DistributionGroupMember "Live Presidents" Seems that we should be able to create a PowerShell script that runs the cmdlet, and be able to call that from the command line, and thus just call it from within the program. Does this sound correct? If so how would I go about this? Thanks. Answer can be language agnostic, but Visual Basic would probably be best since that is what I loaded the test web service up in.

• GUI toolkit for Unicode text app?

  - by wrp

  In developing a tool for processing text in exotic scripts, I'm having trouble choosing a GUI toolkit. The main part of the interface is to be a text editor, not much more elaborate than Notepad, but with its own input method editor. It is to be extensible in a scripting language so that non-programmers can develop their own input methods and display routines. It will be assumed that all files are UTF-8. More elaborate support like regexes is not needed. The main sticking points are: characters beyond the Basic Multilingual Plane right-to-left and bi-directional text extension in a scripting language cross-platform Linux/Windows/OS X My first choice was Tcl/Tk, but it lacks bidi and going beyond the BMP seems dodgy. At the other extreme, I've considered Qt with embedded ECMAScript, but that might be heavier and less malleable than I would like. I'm even thinking about making it browser based, but I'm concerned that the IM for large scripts would be too heavy for client-side processing. I've also looked at a few similar projects in Java, but the quality of the font rendering in SWING has been unacceptable. What are your experiences in handling Unicode with various toolkits? Are there other serious issues I haven't considered? What would you recommend for doing this in the lightest way?

• Databinding a StructuredPropertyEditor specific to type and target in Spring(Grails) - Selective app

  - by Colin Harrington

  Using Grails 1.2.2, I'm working on binding a structured property (CC expiration Date) to a java.util.Date but only for specific Domain and Commands objects. I've found the StructuredPropertyEditor interface, but the only way that I've found to register it is to use the PropertyEditorRegistrar and register the editor for the java.util.Date class (much like this example) I don't want all of my dates to use my custom StructuredPropertyEditor. How do I apply the StructuredPropertyEditor selectively to specific targets like certain Command & Domain Classes?

• WinForms app config manager is x86 and cannot reference assemblies that targets Any CPU

  - by ivos

  Hi I'm using Win7 64x and Visual Studio 2010. I created a library/framework targeting Any CPU. Then I created a new WinForms project that uses that framework, leaving the default values of the wizard. I mean, I didn't change anything. When I reference my framework, VS cannot find the assemblies. If I go to the project properties, it is targeting Any CPU (as expected, I can change it if I want). But if I go to Configuration Manager, the only choice I have for that project is x86. And I guess that is the problem. I tried to add Any CPU as a new Target but I was unable to. Could someone help me? :) Thanks in advance!

• Debugging into a shared library source from consuming app, using QTCreator

  - by morpheous

  I am using QTCreator (1.3.1) on Ubuntu Karmic. I have built two projects: a shared library an application that links to the shared library I am debugging the application, and need to step into the implementation (i.e. the source) of one of the functions exported by the shared library. Does anyone know how to setup the QTCreator to allow me to step into the source of a shared library?

• Is it possible to build a WinForm app (or another type of .NET app) which allows me to interact with

  - by RoboShop

  I'm learning Chinese at the moment and I have gotten my hand on a Chinese dictionary definition. Now I would like to make an interface. All I really want the application to do is when I point my mouse pointer over any text on the screen (in any window), it would identify the text I am pointing at and then display a small form over it, which would the chinese transaction. Is that possible to do? Can WinForms apps interact with windows outside of it's own application?

• WindowsForms difference to simple Console App

  - by daemonfire300

  I currently started to "port" my console projects to WinForms, but it seems I am badly failing doing that. I am simply used to a console structure: I got my classes interacting with each other depending on the input coming from the console. A simple flow: Input -> ProcessInput -> Execute -> Output -> wait for input Now I got this big Form1.cs (etc.) and the "Application.Run(Form1);" But I really got no clue how my classes can interact with the form and create a flow like I described above. I mean, I just have these "...._Click(object sender....)" for each "item" inside the form. Now I do not know where to place / start my flow / loop, and how my classes can interact with the form.

• New App provisioning in iPhone SDK 4 Beta

  The enterprise distribution in iPhone 4 beta is supposed to be easier. Companies can host their own servers with the apps instead of distributing through iTunes. I am looking for technical information on how to do this. Can someone refer to the documentation/online details regarding this? Thank much.

• Netbean6.8: Cant deploy an app if I have Message Driven Bean

  - by Harry Pham

  I create an Enterprise Application CustomerApp that also generated two projects CustomerApp-ejb and CustomerApp-war. In the CustomerApp-ejb, I create a SessionBean call CustomerSessionBean.java as below. package com.customerapp.ejb; import javax.ejb.Stateless; import javax.ejb.LocalBean; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; @Stateless @LocalBean public class CustomerSessionBean { @PersistenceContext(unitName = "CustomerApp-ejbPU") private EntityManager em; public void persist(Object object) { em.persist(object); } } Now I can deploy CustomerApp-war just fine. But as soon as I create a Message Driven Bean, I cant deploy CustomerApp-war anymore. When I create NotificationBean.java (message driven bean), In the project destination option, I click add, and have NotificationQueue for the Destination Name and Destination Type is Queue. Below are the code package com.customerapp.mdb; import javax.ejb.ActivationConfigProperty; import javax.ejb.MessageDriven; import javax.jms.Message; import javax.jms.MessageListener; @MessageDriven(mappedName = "jms/NotificationQueue", activationConfig = { @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") }) public class NotificationBean implements MessageListener { public NotificationBean() { } public void onMessage(Message message) { } } If I remove the @MessageDriven annotation, then I can deploy the project. Any idea why and how to fix it?

• Haxe app and Gtk-WARNING on linux servers

  - by Cambiata

  Hi! I'm trying a Haxe-compiled solution called FAR (Flash Archiver) created by Edwin Van Rijkom (http://code.google.com/p/vanrijkom-flashlibs/) wich uses a command-line tool for creating compressed archives. When running the FAR tool locally on my ubuntu laptop, everything works fine. When running remotely (terminal as Root) on my Ubuntu and Debian servers, it gives the following error: Gtk-WARNING **: cannot open display: I've tried to reach Edvin about this, but no response so far. Maybe it has something to do with installation or user rights on the server? Any clue?

• How can I launch QuickTime from my app?

  I am trying to load a video from the web, but am having trouble getting it to appear in QuickTime. I can only hear the audio. I would like it to launch QuickTime. - (void)loadView { NSURL *movieURL = [NSURL URLWithString:@"http://movies.apple.com/media/us/mac/getamac/2009/apple-mvp-biohazard_suit-us-20090419_480x272.mov"]; if (movieURL != nil) { moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; moviePlayer.initialPlaybackTime = -1.0; // Register to receive a notification when the movie has finished playing.

• Browser-based application or stand-alone GUI app?

  - by crystalattice

  I'm sure this has been asked before, but I can't find it. What are the benefits/limitations of using a browser-based interface for a stand-alone application vs. using a normal GUI framework? I'm working on a Python program currently implement with wxPython for the GUI. The application is simply user-entry forms and dialogs. I am considering moving to PyQt because of the widgets it has (for future expansion), then I realized I could probably just use a browser to do much of the same stuff. The application currently doesn't require Internet access, though it's a possibility in the future. I was thinking of using Karrigell for the web framework if I go browser-based. Edit For clarification, as of right now the application would be browser-based, not web-based. All the information would be stored locally on the client computer; no server calls would need to be made and no Internet access required (it may come later though). It would simply be a browser GUI instead of a wxPython/PyQt GUI. Hope that makes sense.

• Sencha touch 2/ app workflow with navigation view

  - by eplatonov

  I am trying to understand how can I implement the same functionality which provides navigation view in sencha touch 2, but .... Each item of the 'Ext.NavigationView' component should have it's own unique set of 'navigationBar' elements. I mean set of buttons, for example. I know that I can do something like this: this.getMain().getNavigationBar().rightBox.removeAll(); this.getMain().getNavigationBar().rightBox.add(this.getSettingButton()); //where 'getSettingButton' predefined by me a button And do this action each time when 'push' event happens (clear 'navigationBar' and add appropriate set of buttons) Of course, I even can implement 'Ext.Panel' with 'layout: card' and set of 'Ext.panel' elements in the 'items' property, each of which will be have unique 'toolbar'. To control the behavior I can use 'setActiveItem' method. But, I think each of these approaches is a bit weird, isn't it? I expected that would be much more natural approach to implement it. Most likely I don't know what I need. Confirm my doubts. What is the best way to do it.
